## Description

The Silicon One team at Cisco creates innovative hardware platforms central to the AI era, powering core Switching, Routing, and Wireless products for organizations globally.

As a Silicon Characterization Engineer, you will drive the resolution of complex silicon performance and characterization issues through deep, multi-functional collaboration with architecture, design, and software teams. You will leverage these technical insights to provide critical feedback that directly influences the design, debuggability, and architectural specifications of future silicon components.

Key responsibilities:

- Lead the Electrical Post Silicon Validation efforts for Silicon One products, focusing on high-speed and power-intensive devices.

- Collaborate with multi-functional teams to drive the silicon validation process, from architecture through to physical design and DFT.

- Analyze and interpret characterization data to guide design improvements and ensure product excellence.

- Develop and execute test plans to validate silicon performance and reliability against stringent specifications.

- Troubleshoot and resolve issues related to silicon performance and characterization.

Requirements:

- B.Sc. in Electrical or Computer Engineering/ Equivalent.

- 5+ years of experience in silicon and package characterization, hardware bring-up, or multi-disciplinary system-level validation in an R&D lab environment.

- Proficiency with high-speed scopes, VNA, TDR, and phase noise analyzers.

- ASIC bring-up on EVBs, specifically focusing on SerDes and high-speed clock/voltage domains.

- Experience developing validation plans and automation scripts in Python.

Preferred qualifications:

- Ability to root-cause issues that jump between the silicon, the package, and the PCB.

- Deep understanding of signal and power integrity (jitter, supply noise, and channel design).

- Background in high-speed optical-electrical validation, including optical eye-diagram analysis, BER testing, and optical-to-electrical SerDes interfaces.

- Familiarity with electro-optic integration, Co-Packaged Optics (CPO), or optical transceiver module bring-up and test methodologies.

- Background in using validation data to drive improvements in production flow and chip yield.
